    Study Notes

    Neurotransmitter Synthesis and Breakdown

    • Acetylcholine (ACh) is synthesized from choline and acetyl coenzyme A (acetyl-CoA) in the presynaptic neuron.
    • Acetylcholinesterase breaks down Acetylcholine (ACh) into choline and acetate in the synaptic cleft.

    Dopamine Synthesis

    • Dopamine is synthesized from the amino acid tyrosine.

    Serotonin Synthesis and Release

    • Serotonin is synthesized from the amino acid tryptophan.
    • Action potentials in serotonergic neurons lead to the release of serotonin into the synaptic cleft.

    Dopamine Reabsorption

    • Dopamine transporters are responsible for reabsorbing dopamine or breaking it down in the synaptic cleft.
